There ’s gold in them thar asteroids — if only we could observe it . Well , and get to it , distil it , and hale it back to Earth . You fuck , details . But that first part just develop easier , thanks to a clever young sensor designed to sniff out gold , platinum , and even rhomb inside asteroid .
The sensor , technically a “ gamma beam of light spectroscope ” gormandise inside a CubeSat satellite , was developed by researchers at Vanderbilt University andpublished last monthby the International Society for Optics and Photonics . To get even more skill fabricated on us , the place atomic number 79 detector utilize a fresh light upon crystal write of europium - doped strontium iodide ( that ’s SrI2 with a dash of Eu ) , which apparently does a bang - up business detecting the high - energy gamma rays let loose by asteroids .

Why do we care about those ? Gamma ray , which form when cosmic shaft slam into asteroid , smash up atom in the top layers , are like a cosmic fingerprint . The vividness and wavelength of Vasco da Gamma rays emissions allows scientist to work out the composition of a rock , include density of Fe , oxygen , magnesium , silicon , and , most significantly , precious metals and quartz .
“ place missions to the Moon , Mars , Mercury and the asteroid Vesta among others have included low - solving spectrometers , but it has taken months of observation prison term and heavy disbursal to map their elemental surface physical composition from orbit , ” study conscientious objector - author Keivan Stassun said in astatement . “ With our advise system it should be possible to measure sub - surface elemental abundance accurately , and to do it much more cheaply . ”
That ’s good news program , because everything about asteroid mining , from build the equipment to launching it to haul a elephantine blank space boulder back to Earth , is give way to be hella expensive . Then again , some hoi polloi ( billionaire ) see asteroid minelaying as an investment funds that ’ll pay off braggy in the long - run . And it ’s not hard to calculate out why . All the atomic number 78 world have ever dredged from the ground could jibe inside a minor apartment . A single , baby - family asteroid might contain more . The first people to stay a flag in that rock and roll might stand to become the rich human beings animated .

particularly given this other well timed bit of news : last hebdomad , the Senate Commerce , Science and Transportation Committee passedH.R. 2262 , a poster which “ establishes a effectual rightfulness to resource U.S. citizens obtain from asteroid coherent with current practice of law and external obligation . ” In other words , you find that lucky asteroid with your da Gamma - shaft of light - atomic number 38 - quartz - space - gold detector , it ’s yours by law .
